Watch the explosion here:
Challenger exploded after taking off at 'Kennedy', 33-years ago, tomorrow.
If you listen to the clip above, they state Challenger was the 25th mission.
Challenger exploded January 28, 1986.
Recall, the Columbia shuttle disaster happened during its 28th mission.
They say 7 people were killed in the Challenger disaster.
1+2+3+4+5+6+7 = 28
*As for STS-107 in Columbia... 107, the 28th prime.... Military = 107
As for 73-seconds...
73 seconds can also be expressed as 1:13, like 113...
Notice this story is from the perspective of Scobee.
NASA was established on a date with 113 numerology.
7/29/1958 = 7+29+19+58 = 113
Of course, 113 is the number of the Scottish Rite.
Columbia was NASA's 113th mission.
